Abstract

An electronic device including an electronic module, a sensing unit divided into a hole area overlapping the electronic module, an active area surrounding the hole area, and a peripheral area adjacent to the active area. A first sensing electrode and a second sensing electrode are disposed in the active area and insulated from each other. The first sensing electrode includes first main patterns, first neighboring patterns having a smaller area than the first main patterns, and a hole pattern connected to the adjacent first neighboring patterns. The second sensing electrode includes second main patterns, second neighboring patterns adjacent the hole area and having a smaller area than the second main patterns, second connection patterns connected to the second main patterns, and a routing pattern connected to the adjacent second neighboring patterns. The hole pattern is disposed in the hole area, and the routing pattern is disposed in the peripheral area.
